Iran is pretty much surrounded by nuclear states - Russia, India, Pakistan, Israel, and now US-occupied Iraq. Is it any wonder they feel a bit nervous? Events in Lebanon suggest that Israel is the nearest of these to a rogue state, liable to overreact disproportionately to the slightest offence, kept in check chiefly by deference to Washington... which is of course the only country that's ever actually used nuclear weapons. None of this makes me feel comfortable, but Iran doesn't, in my eyes, make matters very much worse.
